SASH-FASTENER.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed June 9, 1905. Serial No. 264,513.

To all whom, it may concern.-

Be it known that I, AARON WASHINGTON DUNN, a citizen of the United States, residing at Lampasas, in the county of Lampasas and State of Texas, have invented a new and useful Sash-Holder, of which the following is a specification.

This invention relates to improvements in sash-holders, and has for its object to improve and simplify the construction and in crease the utility of devices of this character.

With these and other obj ectsin view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed. I

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advan' tages.

In the drawings thus employed, Figure 1 is a sectional view of portions of a windowframe and the sashes operative therein with the improvement applied. Fig. 2 is a front elevation, enlarged, of the improved device detached. Fig. 3-is a longitudinal section, enlarged, of the improved device detached. Fig. 4 is a perspective view of the base member, and Fig. 5 is a perspective view of 'the stop, member detached. Fig. 6 is a view similar to Fig. 5, illustrating a slight modification in the construction of the stop member of the device. I

The improved device may be applied to any portion of the sash, but is preferably attached upon the upper member of the lower sash (represented at 10) for operating against the upper sash, (represented at 1 1,)and consists of a base member 12, having spaced guide members 13 14 at the sides and a rigid stand ard 15, extending from the rear end and provided with a screw threaded opening 15. The base member is also provided with screwapertures 16 forthe reception of the holdingscrews, as at 17 18.

Slidably disposed between the guide members of the base is a stop member 19, with a rigid oifset 20 at one end and provided with the serrations 21 in the outer face and a socket 22 in the rear face and grooves 13 and 14 for engagement with the guides 13 and 14.

Operating through the threaded standard 15 is a clamp-screw 23, engaging the socket 22 at one end and with a thumbplate 24 at the other end. The inner end of the screw member 23 is provided with an annular channel 24, with which a pin 25, extending through the member 20, engages to hold the screw from displacement while permitting free rotary movement of the same. By this simple arrangement it will be obvious that when the screw member is rotated in one direction the member 20 will be firmly compressed against the sash 11 and effectually lock both sashes from movement.

The device is simple in construction, can be inexpensively manufactured and applied to any of the various forms of sashes manufactured, and will operate effectually for the purposes described.

If preferred, the serrations 21 on the stop member may be replaced by a rubber, felt, or other flexible pad, as at 26 in Fig. 5, and sup ported in a recess 27 in the vertical portion 20 of the stop member; but this would not be a departure from the principle of the invention, as the same results would be accomplished in substantially the same manner.

The flexible )ad will be employed upon the i more finely 'nished sash or frames to avoid marring or scratching the same.

Having thus described the invention, what is claimed is- 1. A sash-holder comprising a base mem her having means for attachment to a window and provided at one end with a standard having a threaded aperture and with spaced longitudinal guide members, a stop member slidably disposed between said guide mem bers and having longitudinal grooves for engaging the same, said stop member having a rigid extension provided with a socket in the rear face, and a clamp-screw operating through said threaded aperture in said base standard and rotatively engaging the socket in said stop-member extension.

2. A sash-holder comprising a base memher having means for attachment to a window sash, a standard rigidly upstanding from one end of the base member and provided With a threaded aperture, inturned In testimony that I claim the foregoing as guide-flanges formed along the ed es of the my own I have hereto afliXed my signature in 10 base member, a stop member slidabiy mountthe presence of two Witnesses.
